The Apple WWDC 2013 is finally started, everyone know that it is the time that the iOS 7 unveils. At last, the iOS 7 was announced with new user interface.

iOS 7 brings a brand new looking for it own UI and the icons look more simple and nice. All system icons are redesigned around a standardized grid to unify the look. iOS 7 also brings animated wallpaper but not quite a live wallpaper and there's a dynamic parallax effect between the icons and the wallpaper as you turn and tilt your phone.

Here's the promo video of iOS 7:

iOS 7 has a brand new lock screen which looks familiar from Android and BlackBerry 10 lock screen. There’s also new floating bubble live wallpaper and translucent UI effects to make it more aesthetically refreshing than before. iOS 7 features Control Center and Notification Center, just a simple scroll up from down to activate the Control Center and scroll down from up to activate the Notification Center.

Control Center gives you quick access to the controls and apps you always seem to need right this second. Just swipe up from any screen - including the Lock screen - to do things like switch to Airplane mode, turn Wi-Fi on or off, or adjust the brightness of your display. You can even shine a light on things with a new flashlight. Never has one swipe given you so much control.The Notification Center lets you know about new mail, missed calls, to-dos that need doing, and more. And a new feature called Today gives you a convenient summary of, well, today. One glance at your iPhone and you’ll know if it’s a certain someone’s birthday, if you’ll need an umbrella, or if traffic will slow down your commute. You’ll even get a heads-up on tomorrow. You can access Notification Center from any screen, including the Lock screen. Just swipe down. And get up to speed.

Next, Multitasking has also changed to horizontal carousel look which looks similar to the Multitasking that found on Windows Phone 8. Multitasking has always been a smart way to switch between apps. Now it’s even smarter. Because iOS 7 learns when you like to use your apps and can update your content before you launch them. So if you tend to check your favorite social app at 9:00 a.m. every day, your feed will be ready and waiting for you. That’s multitasking in iOS 7. It knows what you want to do before you do.

The Safari web browser has been revamped as well with a unified tool bar for a simplified look. Browsing is bigger, better, and more beautiful with Safari in iOS 7. Buttons and bars — like the unified smart search field — stay hidden until you scroll to reveal them. So you see more content than ever on your screen. And with a swipe, you can go back or forward a page. It’s all designed so nothing gets in your way or slows you down.

Unified smart search field

Type a URL or search term in the unified smart search field, and Safari automatically suggests the closest match to what you’re looking for. So you find the right web page fast.

New tab view

See your open web pages in a consolidated view that lets you scroll effortlessly from tab to tab. To close a page, just swipe it off screen.

Shared Links

See all the URLs in your Twitter timeline, who posted them, and what they had to say about them.

Reading List

Reading through the articles in your Reading List is quick and easy. Simply scroll seamlessly from one to the next.

iCloud Keychain

Lots of things you do on the web require passwords. Now iCloud can remember your account names, passwords, and credit card numbers for you. And Safari can enter them automatically whenever you need to sign in to a site or shop online. It works on all your iOS 7 devices and your Mac computers running OS X Mavericks. And with 256-bit AES encryption, it’s highly secure.

Password Generator

Every time you create an account, you can have Safari generate a unique,hard-to-guess password. And remember it for you.

Apple add a new feature in iOS 7, although Apple has yet to adopt NFC, sharing files among Apple devices is still possible through Air Drop. Enter Air Drop for iOS. It lets you quickly and easily share photos, videos, contacts — and anything else from any app with a Share button. Just tap Share, then select the person you want to share with. Air Drop does the rest using Wi-Fi and Bluetooth. No setup required. And transfers are encrypted, so what you share is highly secure.

Camera in iOS 7 puts all your shooting formats — still, video, panorama, and now square — front and center. With a swipe, you can capture what you want the way you want. Fast. And new filters let you do even more with each image.

The filters are including Mono, Tonal, Noir, Fade, None, Chrome, Process, Transfer, Instant and you can set in none. You can apply filters to still and square photos. Pick a filter and see the effect before you take the picture. Or just take the shot and apply it later. If you ever change your mind and decide no filter is the best filter, you can simply remove it.

Siri in iOS 7 gets a new look, a new sound, and new capabilities. It features a redesigned interface that fades into view — on top of whatever’s on your screen. A more natural speech pattern — in a new female or male voice — is even easier to understand. Siri is faster at answering questions and checks more sources, such as Bing, Wikipedia, and Twitter. And it takes on extra tasks, like returning calls, playing voice-mail, controlling iTunes Radio, and more.
